FILTER FOR WINES OR OTHER LIQUIDS.

SPECIFICATION formingpart of Letters Patent No. 660,921. dated October30, 1900. Application filed September 8, 1899. Serial No. 729,870. (Nomodel.)

To all whont it may concern:

Be it known that I, GASTON PERAUD, a citizen ot' the Republic of France,residing at La Rochelle, France, have invented certain new i referenceto the accompanying drawings, in.

which Figure 1 shows the mannerin which one of the filtering tubes orhose is constituted. Fig. 2 represents the apparatus when mounted inextern al elevat ion. Fig. 3 is an internal view of the apparatus inelevation, the ves el containing the whole of the filtering-tubes beingin section. Fig. eisavertical section through the apparatus as a Whole;and Fig. 5 is a plan view of the apparatus, the cover being 'removed. 7

This filter is essentially constituted by'a hose or tube formed of asuitable fabric and spirally wound in the manner of a serpentine coil,and into this tube the liquid to be filtered is conducted. This liquidtraverses the wall of the tube from its interior toward its exterior andis thus filtered. By establishing an apparatus consisting of severalcoils of decreasing diameters in such a manner that they are adapted tofit one within the other a filter having a very large surface andfurnishing a considerable flow is formed. Each coil is constituted by aframework or body A, upon which is passed a sleeve or tube of filteringfabric B, Fig. 1, such framework forming an internal support for thistube. The framework A may be of any suitable kind, such as wicker, cane,met-a1 wire, or perforated metal. Upon this framework is arranged thesleeve of suitable filtering fabric B, which is of such a width as notto fit 5o tightly against the framework and of greater length than thislatter, so that upon being reduced to the length of thesupporting-framework it becomes plaited or gathered. A tube of filteringfabric is thus obtained which presents a very large surface. Fig. 1shows the various phases of the construction of such a tube. The tubethus formed is wound spirally in order to form a coil and is placedbetween two cylindrical supports (1 C, which maintain it. These supportsmay be of wicker, cane, perforated metal, or the like, so that althoughaffording support to the coil they do not impede the circulation of theliquid in the vessel in which the coil is arranged. Within thecylindrical space remaining vacant a second coil of suitable diameter,established in the same manner and likewise maintained between twosupports 0 O, is arranged, then a third coil, and so on until the entirespace isfilled.

It is obvious that any desired number of coils may be provided. Thiswill depend upon the filtering-surface which it is desired that 'theapparatus should furnish. These coils,

maintained by their supports 0 O, are placed in a vessel D, closed by acover E, through which pass the upper extremities of the various coils,each of which terminates in a cock F. These dilferent cocks F F F areconnected by pipes G G with a single pipe H, through which the liquidwhich it is desired to filter enters. At their lower portion the coilsterminate in a pipe I, which passes outside the vessel and is providedwith a cock J. The various supports 0 C, maintaining the coi s, areretained in position by a partition K, arranged in the lower portion ofthe vessel.

Upon-the cover E of the vessel, which hermetically closes this latter,is adapted the cock L, serving for the discharge of the filtered liquid,and also a pipe M for the liberation of air and carbonic acid. Thevessel is provided at its lower portion with a drain cock or bung N.

are closed and the cock upon the pipe I and also the drain-cock N areopened. The coils and the vessel are thus emptied, whereupon the cock Fof one of the coils is opened. The liquid in passing through thiscarries with it the principal part of the lees or dregs, and the wholepasses into the pipe I. This coil is therefore cleansed and its cock Fis closed. The same procedure is adopted with all these coils. \Vhenthecleansing operation has been completed, the cock J upon the pipe Iand the drain-cock N are closed and the cocks F F of the coils and alsothe cock are opened, whereupon the apparatus is again renderedoperative.

It should be understood that I reserve the right to introduce into theapparatus above described any alterations or modifications whereby theprinciple of the device is not af fected. Thus,t'orexatnple,Ireservetheright to establish the apparatus with anydesired number of filtering-tubes. I do not confine myself to arrangingthese filtering-tubes in the trough in the form of coils. They may bearranged in any suitable manner.

Having now particularly described and ascertained the nature of my saidinvention and in What manner the same is to be performed, I declare thatwhat I claim is A filter for liquids consisting of a vessel containing anumber of tilteri ng-tubes formed by a sleeve or tube of approtjn'iatefabric and a supportiug-framework for the fabric, which fabric isplaited or gathered upon this framework, as and for the, purposedescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
